Under normal market conditions, the Fund seeks to maintain a positive overall portfolio duration. For purposes of the Funds 80% policy, bonds include derivative instruments or other investments that have economic characteristics similar to bonds. Bonds include debt obligations of any maturity, such as bonds, notes, bills and debentures. The Fund invests predominantly in bonds issued by governments, government-related entities and government agencies located around the world. Bonds may be denominated and issued in the local currency or in another currency. The Fund may also invest in securities or structured products that are linked to or derive their value from another security, asset or currency of any nation. In addition, the Funds assets are invested in issuers located in at least three countries (including the U.S.). The Fund may invest without limit in developing markets. The Fund is a "non-diversified" fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund. Although the Fund may buy bonds rated in any category, it focuses on "investment grade" bonds. These are issues rated in the top four rating categories by at least one independent rating agency, such as S&P Global Ratings (S&P ) or Moody's Investors Service (Moody's) or, if unrated, determined by the Fund's investment manager to be of comparable quality. The Fund may invest up to 25% of its total assets in bonds that are rated below investment grade or, if unrated determined by the investment manager to be of comparable quality. Generally, lower rated securities pay higher yields than more highly rated securities to compensate investors for the higher risk. The Fund may invest in debt securities of any maturity, and the average maturity of debt securities in the Funds portfolio will fluctuate depending on the investment managers outlook on changing market, economic, and political conditions. For purposes of pursuing its investment goals, the Fund regularly enters into various currency related transactions involving derivative instruments, principally currency and cross currency forwards and currency options, but it may also use currency and currency index futures contracts. The Fund maintains extensive positions in currency related derivative instruments as a hedging technique or to implement a currency investment strategy, which could expose a large amount of the Funds assets to obligations under these instruments. The results of such transactions may represent, from time to time, a large component of the Funds investment returns. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposure to selected currencies. For purposes of pursuing its investment goals, the Fund regularly enters into interest rate swaps and may also enter into various other transactions involving derivatives, including interest rate/bond futures and credit default swaps. These derivative instruments may be used for hedging purposes, to enhance returns, or to obtain net long or net negative (short) exposure to selected, interest rates, countries, durations or credit risks. When choosing investments for the Fund, the investment manager allocates the Fund's assets based upon its assessment of changing market, political and economic conditions. It considers various factors, including evaluation of interest rates, currency exchange rate changes and credit risks. The investment manager may consider selling a security when it believes the security has become fully valued due to either its price appreciation or changes in the issuer's fundamentals, or when the investment manager believes another security is a more attractive investment opportunity. The Fund may, at times, maintain a large position in cash and cash equivalents (including money market funds). Show less
